and may even burn the welding machine.
Prohibit high voltage！

The power supply voltage is listed in the "main performance parameters" table.
Under normal circumstances, the automatic voltage compensation circuit in the welding
machine will ensure that the welding current is kept within the allowable range. If the
power supply voltage exceeds the allowable value, the welding machine will be
damaged. The user should fully understand this situation and take corresponding
preventive measures.
It is forbidden to use the welding machine for thawing.

A ground screw is attached to the back of each welder and marked with a ground
5
mark. Before use, select a cable with a cross section greater than 4mm2, and reliably
ground the welding machine shell to discharge static electricity or prevent accidents that
may occur due to leakage.
If the welding machine exceeds the standard load continuity rate, the welding
6
machine may suddenly enter the protection state and suspend work. This means that the
welding machine exceeds the standard load continuity rate. If the temperature is too high,
the temperature control switch will be triggered to stop the welding machine. The yellow
indicator light on the front panel lights up. In this case, you do not have to unplug the
power plug, so that the cooling fan can continue to cool the welder. When the yellow
indicator light goes out, the temperature drops to the standard range and welding can be
restarted.
